LoganTree, LP v. Apple, Inc. DC

After hitting Fossil (Misfit) and Huawei in its revived wearables campaign in March, inventor-backed LoganTree LP has filed new cases against Apple (6:21-cv-00397) in the Western District of Texas and LG Electronics (LGE) (4:21-cv-00332) in the Eastern District of the same state. A single patent generally related to monitoring human physical activity is asserted throughout, the claims of the patent having survived several inter partes reviews (IPRs) and having been construed in a January 2021 Markman order from District of Kansas Judge Eric F. Melgren, who is presiding over an earlier case, against Garmin.

LoganTree LP has filed new litigation in the wearables campaign that it began back in 2015, suing Fossil (Misfit) (1:21-cv-00385) in the District of Delaware and Huawei (6:21-cv-00119) in the Western District of Texas over the same patent. The suits follow a claim construction ruling in a long-stayed dispute with Garmin that sprung back to life after unsuccessful inter partes reviews (IPRs) of the patent, which generally relates to monitoring human physical activity.
